During a Tuesday performance in Berkeley, lead singer Thom Yorke realized something was wrong and muttered, “Aw sh–” into the microphone. He did power through “Give Up the Ghost,” but Jonny Greenwood soon made light of the situation, adding a comedic element to the performance.

The guitarist captured the soundbite of Yorke’s frustration and looped it in over and over, much to the amusement of the singer and crowd.

Last Friday, the issues weren’t so funny, as the band was forced to leave the stage a couple times during their headlining performance at Coachella, before ultimately being able to finish.
